How to use refrigerant in industrial refrigerator

Refrigerant is an indispensable part of industrial refrigerators, and it acts like blood in the human body. Since various refrigerants have different physical and chemical properties, they have different saturation pressures at different temperatures. What should you pay attention to when using or storing refrigerants in industrial refrigerators?

　　 At room temperature, some industrial refrigerator refrigerants have high pressures and some have low pressures. However, no matter what the pressure is, all kinds of refrigerant cylinders are pressure vessels. Be careful when using them. Because the various refrigerants of industrial chillers have different properties, most of them are explosive. If the refrigerant cylinder is corroded, not inspected, or exposed to sudden exposure to the outside world, or fire, it is very easy to explode, and some refrigerants are toxic. Therefore, the storage and handling of industrial refrigerator refrigerants , Use must be careful and then careful.

No matter what kind of refrigerant, after using up, be sure to close the cylinder valve immediately. When the industrial refrigerator system is overhauled, if the refrigerant is pumped out from the industrial refrigerator system and pressed into the cylinder, it should be sufficiently cooled , And strictly control the weight of the injected cylinder, and never fill it up. Under normal circumstances, it should not exceed 60% of the volume of the steel cylinder, allowing the refrigerant of the industrial refrigerator to expand at room temperature.

　　 In addition, when using halogen lamps to detect leaks in industrial refrigerator refrigeration systems, if the color changes, after determining the leak point, the suction mouth should be removed immediately to avoid phosgene poisoning.
